中文摘要：

综合电力系统是典型的多相交直流混合电力系统，多由多相电机和电力电子设备构成。由于多相电机计算量大、端口数多，采用传统并行算法难以提高综合电力系统电磁暂态仿真效率，为此提出一种混合并行算法，该算法由元件级并行和网络级并行2部分组成。其中前者通过将计算量大的多相电机元件分拆为多个互相耦合的电机，以大幅减少单个元件的计算量和显著提高系统分区的灵活性；后者则利用元件级并行实现系统切分方案的优化设计和计算流程中等待时间的高效利用，从而显著提高网络并行计算的总体效率。典型综合电力系统算例的仿真结果验证了所提出算法的正确性和有效性。

英文摘要：

The integrated power system is a typical hybrid AC/DC power system, which usually consists of multi-phase motors and power electronic devices. Because of the many electrical ports used, the multi-phase motors are hard to be decomposed optimally for parallel computing, which limit the speedup of the electromagnetic transients simulation of the integrated power system. In this work, a hybrid parallel simulation algorithm was proposed, which is based on both component and network decomposition. Through dividing multi-phase motor into several small motors, the proposed algorithm makes the overall system partitioned more flexibly and balanced. Furthermore, the parallel computation flow is optimized also to reduce the synchronization costs and make full use of the computational resources. Test results of a typical integrated power system were presented to validate the efficiency and accuracy of the proposed algorithm.
